ED80 "collar" on the focuser

[Rob]

How about those Baader links to Alpine Astro?... is that a poss solution?

[Milamber]

yes, but what's wrong with the scopestuff ones?

[Rob]

Don't know.... finess and technology (sorry I'm a sucker for new stuff)

[Milamber]

Don't the Baader ones only do 1.25", and detract from the in-travel too?

[Rob]

Humm.. yep your right there. I may have to pay loads from the USA. Blast

The scopestuff looks exactly what I need! Thanks again Arthur and speedy recovery!

[A McEwan]

Yep, there's a seperate ring which you tighten the "collar" or visual back against to hold it firm. And yes, there's no way I'd sell my Mercury Systems adapter - it's simply too useful. I sold one once and regreted it when I got the next 'scope! Thankfully I replaced it and that little bit of plastic and copper will never leave me again.

It would be great if these do start being produced in the UK by somebody in the future. Very handy things and a great improvement over the standard items.

Reply back from Jim at Scopestuff: Claims this adapter will not fit my Celestron 80ED. Not to worry. So is the thread on the draw tube an SCT thread?. That could be interesting if it is?.

[Milamber]

No - it's a Synta thread, one they made up all by themselves. SCT is a gnat's under 2"... you're going to need something made specifically for it unfortunately.

PS - would that be the same Scopepestuff that copied the Ambermile 3D Weight system?

[Rob]

To be fair its kinda moving into the 'not worth the hassel' area. if was not for the stupid modern nose pieces on the diagonals these days, it would be fine.

[Milamber]

True - would be nice if they all agreed on one that worked!

[Rob]

Still no further with this!.. Adam at David Hinds is kindly looking into it from a Baader solution point of view. If anyone else knows the tread size on the collar please share it.

I know a few on here would be interested in swapping it out.
